Abstract
A user equipment (UE) may spatial time-division multiplex a plurality of sounding reference signal (SRS) ports, each of the plurality of SRS ports being associated with at least one of a set of orthogonal weights, the set of orthogonal weights corresponding to phase shifting, and transmit a plurality of SRSs via the plurality of spatially time-division multiplexed SRS ports simultaneously, each of the plurality of SRSs including at least two SRS repetition. The plurality of SRSs may be configured to form or present a quasi-co-location (QCL) receive (Rx) beam subspace. The UE may configure the plurality of SRSs to form the subspace as the QCL Rx beam subspace, and a base station may signal the UE to a specific Rx beam subspace such that it is aligned to the base station's beamforming direction, and achieve spatial multiplexing gain in the QCL Rx beam subspace.
